The Extrema Ratio BFK Nano in Avio is a tiny fixed blade knife that takes the BFK's tough tanto design down to an easy-carry minimum. Its 2.13" satin tanto blade is nitrogen-alloyed steel, where the nitrogen adds strength and helps fight corrosion, and the tanto point gives the small blade extra durability at the tip. The blue-gray G10 handle provides a grippy, lightweight hold, and full extended tang construction keeps this 5.5" overall knife surprisingly solid. A lanyard hole adds retention, and a black Kydex MOLLE compatible belt sheath is included, so it works as a neck knife, backup blade or minimalist EDC.
